SPECIFICATION forming part of Letters Patent No. 792,527, dated June 13,1905.

Application filed November 1, 1904. Serial No. 231,001.

To all whom it may concern:

Be it known that I, HARRY. Looxwoon, acitizen of the United States,residing at Jackson, in the county of Jackson and State of Michigan,have invented new and useful Improvements in Faring-Knives, of which thefollowing is a specification.

This invention relates to improvements in paring-knives for paringfruits or vegetables, the objects in view being to provide a knife ofthis character which possesses superior qualities with respect to a moreefficient capability of action to pare or remove the skins of fruits orvegetables with. a minimum waste in the removal of the substance .of thebody of the fruit or vegetable and also in the facility with which itmay be handled to decrease the labor of paring and sharpened to keep itscutting edge in perfect condition for use.

The invention consists in the features of construction, combination, andarrangement of parts hereinafter more fully described and particularlypointed out in the appended claims, reference being had to theaccompanying drawings, in which Figure 1 is a perspective view of aparingknife embodying my invention looking toward the concave side ofthe body of the knife. Fig. 2 is a similar view looking toward theconvex side of the body and showing the slot therein and cutting edge ofthe paring-blade, and Fig. 3 is a cross-section on the line 3 3 of Fig.2.

Referring to the drawings by reference-numerals, 1 represents asuitablehandle, to which is secured one end of a concavo-convex blade 2, theopposite end of which is pointed or otherwise suitably reduced andsharpened to form a cutting portion 3, which may be employed for pittingand removing eyes and other bad spots on fruits and vegetables.

The blade 2 forms the body portion proper of the paring-knife, anddisposed within the chamber formed upon the concaved side thereof is aconcavo-convex cutting-blade 4, having upon one of its side edges acutting edge or projection. 5, which extends through a longitudinal slot6, formed in the side and adjacent to the lower edge of the body 2. Theinner surface of the body 2, adjacent to the upper portion of the slot6, is beveled or tapered, as indicated at 7 to facilitate adjustment ofthe blade 4 and adapt the cutting edge 5 to project at a pointsufficiently above the body wall of the slot 6 to leave an interveningspace or passage through which the parings may feed to the concaveportion of the body 5 and thence discharge, this operation preventingthe parings or peelings from accumulating around the cutting edge of theblade or outer surface of the knife and interfering with the cuttingaction of said blade and the proper manipulation of the knife. Thecutting edge 5 terminates at each end inside the adjacent end of thebody of the blade 4 to cause the production of shoulders 8, which extendbeyond the end portions or limits of the slots 6 to form extended guideportions and stops to limit the outward projection of said cutting edge.From the upper edge of the blade t-namely, at the opposite side edge ofsaid blade from the cutting edge 5extends an arc-shaped slottedprojection 9, through which passes a screw 10, the head of said screwbeing arranged to bear against the under side of said extension and theshank thereof projecting upward through an apertured ear or extension 9on the body 2 and receiving a clamping-nut 11, whereby the screw may bedrawn upwardly to hold the blade 4 firmly in adjusted position. The nut11 is provided with a knurled or milled head 12, by which it may beconveniently turned to clamp and release the blade 4:. It will beobserved that this construction permits the blade-4L to be adjusted inthe arc of a circle to the extent of the limit of the slot in saidextension 9 to adapt the cutting edge 5 to be projected at intervals tocompensate for reductions in its surface by repeated sharpenings. Bythis form of fastening connection also the blade 4 may be adjusted toproject the cutting edge 5 a sufficient distance to enable it to besharpened without removing it from the body 2. The form of the body 2,

and particularly of its tapered portion 7, is such as to facilitate thisoperation and to I adapt the blade 4 to lie so that its cuttingporant-LI tion 5 always projects at an angle to the plane of the slot 6to preserve or form the passage referred to to permit the parings orpeelings to pass to the interior of the body 4 and thence discharge.

In addition to the advantages above set forth it will also be apparentthat in using the knife for paring fruits or vegetables the peculiarform of the body 2 permits the same to have a rolling bearing upon thesurface of the fruit or vegetable and to thereby enable the operator toconveniently regulate the position of the cutting edge of the blade 4 tosuit the peculiarities in form or configuration of the fruit orvegetable which is being pared, thus adapting the knife to be socontrolled or regulated in its action that the cutting edge 5 willcleanly and easily remove the skin of the fruit or vegetable withoutcutting down to any material extentinto the substance of the body of thevegetable, thus preventing the waste attendant upon the use ofparing-knives of ordinary construction. During the operation of paringor peeling the cuttings feed through the slot 6 to the concavity orchamber formed by the concavo-convex body 2, and the latter thus forms aguard or housing to prevent the same from becoming entangled with thecutting-blade or interfering with the free manipulation of thecutting-knife by the user. As fast as the paring-blade is reduced bysharpening it may be adjusted to its proper operative position byloosening the thumb-nut l2 and adjusting the blade 4C by means of itsslotted extension 9, after which the parts may be firmly fastenedtogether again by tightening the nut 12, as will be readily understood.Owing to the peculiar form of the body 2 and blade 4 and the advantagesderived therefrom the knife is adapted to peel or pare much faster thanordinary knives and with less inconvenience to the user.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and mode of operation of theinvention will be understood withouta further extended description.Changes in the form, proportions, and minor details of construction maybe made within the scope of the invention without departing from thespirit or sacrificing any of the advantages thereof.

Having thus fully described the invention, what is claimed as new is 1.A paring-knife having a concavo-convex body provided with a slottherein, the concaved side of said body adjacent to one of the walls ofsaid slot being tapered or inclined, a concavo-convex blade disposedupon. the concaved side of the body and having a cutting edge projectingthrough said slot and retained at a determinedangle thereto by the saidtapered portion of the body, said blade also being provided withshoulders beyond its cutting edge to limit the projection of said edge,and means for adjustably securing the blade to the body.

2. A paring-knife having a concavo-convex body provided with a slottherein, a concavoconvex blade disposed within the concaved side of saidbody and formed with a cutting edge projecting through said slot, saidblade being further formed with shoulders beyond the ends of the slot tolimit the projection of its cutting edge, and means for adjustablysecuring the blade to the body, substantially as described.

3. A paring-knife having a concavo-convex body provided with a slottherein, the concaved side of said body being tapered or inclinedadjacent to one of the walls of said slot, a concavo-convex bladedisposed Within the concaved side of the body and having a cutting edgeprojecting through said slot and bearing against said tapered portion,and also having shoulders beyond its cutting edge to engage the body andlimit the projection of the blade, an arcuate slotted extension upon oneof the edges of the blade, and means cooperating with said extension foradjustably connecting the blade to the body to adapt the blade to beadjusted in an arcuate path.

In testimony whereof I affix my signature in presence of two Witnesses.
